P1633 is a low voltage for the keep alive memory of the computer. It was probably set when the battery was disconnected. The best thing to do is clear the code and rerun the monitors. If you need the monitors to have run for a state emission test, just drive the car.

The code may drop into memory within a week or so and the check engine light will go off. If it doesn't either you still have an issue, you need to clear it with a scantool and it does not reset by itself (which some codes won't)
